Now that MIA is using 3 clubs they are much less crowded for me. The complimentary food and beverage selection is much improved over the years. Plus the ability to take showers on long trips (at those ACs with showers.) What I save alone on food (considering airport prices) nearly pays my annual membership.
The ability to help with travel rebooking tends to be spotty. For some strange reason over the past several years I've had maybe one long delay/misconnect.
